The Library That
Writes Itself

Fabylon is a new programming language, a peer-to-peer publishing platform, and a literary realm — built from first principles for the age of AI. We're offering 49% of the company to investors who believe in what writers can build.

The Problem

Publishing is broken.
Writers deserve infrastructure.

Amazon takes 65% of every ebook sale. Traditional publishers gatekeep who gets read. Self-publishing platforms treat writers as content producers in someone else's machine. The entire infrastructure of literature — from creation to distribution to discovery — is owned by companies that don't read books.

Meanwhile, AI is reshaping everything about how text is created, distributed, and consumed. The tools writers use are not built for this moment. The programming languages that power the internet have no concept of authorship, capability control, or creative sovereignty.

Fabylon starts from a different premise: what if the platform itself was built by and for writers? Not a marketplace — a realm. Not a store — a library that writes itself into existence.

A Language for Safe Powers

Fabylon (.fby) is a capability-first programming language that compiles to WebAssembly. Every module declares what it needs. The host decides what it gets. No ambient authority. LLM-optimized from the start.

A Peer-to-Peer Library

Books are content-addressed, cryptographically signed, and distributed without central servers. Writers publish directly. Readers verify authorship. No middleman takes a cut of the relationship between writer and reader.

A Literary Realm

The Path of the Quill. The Ink & Echo economy. The Lost Folio with 80 collectible cards. Ink Pacts between writers. Divination spreads. A living world where writing is both craft and adventure.

Technology Stack

Not a whitepaper.
Working software.

Architecture — Four Layers

Layer 1

Fabylon Language

Capability-first, Wasm-native, LLM-optimized programming language with full compiler toolchain

Layer 2

Runtime & Broker

Capability policy engine, IR interpreter, WAT codegen, builtin wasm executor, phase gating

Layer 3

Publication Feed

P2P book distribution, Ed25519 signing, content-addressed blobs, AES-256-GCM encryption

Layer 4

The Realm

Ink & Echo economy, Ink Pacts, Path of the Quill, Lost Folio (80 cards), divination engine

Roadmap & Traction

Five phases complete.
Building accelerating.

Phase 1

Language & Compiler

Full lexer, parser, type checker, formatter, WAT codegen. 50+ tests. Spec-complete.

Phase 2

Runtime & Capabilities

IR pipeline, mock runtime, capability broker, wasm interpreter, 200+ tests.

Phase 3

Publication Feed

P2P publishing, cryptographic verification, content-addressed storage, relay protocol.

Phase 4

The Realm

Ink & Echo economy, Ink Pacts, Path of the Quill progression, Lost Folio card system.

Phase 5

Books & Encryption

AES-256-GCM book encryption, entitlement system, paid book distribution, reader states.

Phase 6

Public BetaActive

Onboarding first writers. Building the community. Refining the realm economy.

Phase 7

Marketplace

Paid book marketplace, Ink-to-currency bridge, mobile app, public API.

Phase 8

Scale

Publisher partnerships, translation layer, multi-realm federation.

The Realm

Not just a platform.
A world for writers.

Fabylon's realm layer transforms publishing from a transaction into a journey. Every writer walks the Path of the Quill — twelve levels from "The Blank Page" to "The Quill Eternal." Ink measures what you give to the world. Echo measures what returns. You cannot reach level 7 alone.

Ink & Echo

A dual-currency economy. Ink is earned by creating and sharing. Echo is earned when others engage with your work. Both are cryptographically signed, anti-sybil protected, and locally verifiable.

Ink Pacts

Verifiable invitation chains between writers. Each pact is Ed25519-signed. Up to 3 levels deep. Fragment drops on first-level invites. A trust network built on actual relationships.

The Lost Folio

80 collectible cards in four rarities (40 common, 24 uncommon, 12 rare, 4 legendary). Each card is a 6x6 puzzle of 36 fragments. Realm-signed. Earned through engagement, not purchased.

Divination Engine

Four tarot-style spreads including the Fabylon-original Ink & Echo spread. The cards are inhabited by writers, poets, and the ghosts of literature. Not fortune-telling — depth-finding.

The Path of the Quill — Twelve Levels

INK · 1The Blank Page
INK · 2The First Draft
INK · 3The Returning Writer
INK · 4The Committed Voice
INK · 5The Practiced Hand
INK · 6The Keeper of Deadlines
ECHO · 7The First Echo
ECHO · 8The Read Writer
ECHO · 9The Known Voice
ECHO · 10The Resonant
ECHO · 11The Living Work
ECHO · 12The Quill Eternal

The boundary at level 6→7 cannot be crossed without Echo from others. You cannot reach level 7 alone.

How It Works

Shares in Fabylon represent equity in the company behind the platform. The founder (Martijn Benders) retains 51% of all shares, ensuring long-term creative and technical direction. The remaining 49% is divided across investment tiers.

After completing your investment, you'll receive a detailed investment memorandum, company structure documentation, and a direct conversation with the founder. All investments are subject to standard legal agreements. This is a pre-seed opportunity — you're investing in vision, working software, and a builder.

The Founder

Martijn Benders

Dutch poet, philosopher, and software builder. Author of more than twenty collections published across nine languages. Creator of the Aivelo book production platform and the Fabylon Deck — a writer's tarot inhabited by literary figures and their ghosts.

Benders occupies a rare intersection: a published literary author who also builds production-grade software. Fabylon is not a tech person's idea of what writers need — it's a writer's answer to what technology should be.

The entire Fabylon codebase — compiler, runtime, publication feed, realm layer, encryption system, 37,600 lines of code, 295 tests, 43 alpha releases — is working, tested, architecturally sound software with cryptographic verification, capability-based security, and a fully specified programming language.
